Scala has many useful functions and strengths over Java, but in turn, Scala has a higher learning curve. Java is very beginner-friendly and easy to understand for someone that wants to learn the language, while Scala is more complex due to the functional paradigm and its features.Java is backward compatible while Scala isn’t, meaning that code written in a new version of the language will also be able to run in an older version.As mentioned previously, even though this is preferential, most people consider Java’s more verbose code to be more readable and easier to understand than Scala’s, even if it requires a lot more code.Both Java and Scala have documentation available online, but Java’s goes into more detail on the language’s features and is overall better than Scala’s.
Java’s popularity in itself is also a great thing, especially because you have a bigger community of developers available to help out, as well as a lot more 3rd party libraries.Java doesn’t have the best performance compared to the more popular programming languages on the market, but it does have better performance than Scala.Here are a few of Java’s strengths that Scala doesn’t have: This article has highlighted several of Scala’s features that it has over Java, but Scala isn’t completely infallible.
